SPRINGFIELD -- A snow squall that moved through the region Friday morning has created an unexpectedly slippery commute and police are urging drivers to use caution.

The Massachusetts State Police reported via Twitter that the weather led to several accidents on Interstate 91 near the Connecticut line. Massachusetts Department of Transportation crews had been dispatched to treat the roadway, the agency said.

A rollover accident on Interstate 91 north near exit 49 is causing a backup in the Enfield area. Northbound traffic exited onto Route 5 in Longmeadow, backing up traffic on Longmeadow Street.
